I used to write Java code which didn't have any objects, just byte arrays. It would never call GC and ran lightning fast.

- non-entity 6y agoIs there any particular reason you were using Java then? Seems like you could get the same effect with much more suitable languages.
- pjmlp 6y agoTooling, productivity, developer pool. Usually these are very niche use cases that can be packed into a special purpose library. Check the openHFT repository from my original post.
- pgwhalen 6y agoThe general thinking is that 99% of code at even an HFT doesn’t have to look that funny, so it might make sense to write funny looking java for the 1% that does so you don’t have to fragment your codebase and talent pool.
